you will need a few more defined units in PHY 2054 Units can be treated as algebraic quantities add, subtract, multiply, divide Time remaining = 50 min – 20 min = 30 min Area = width x height = 4 cm x 5 cm = 20 cm 2 e.g., SI unit of area: meter 2 (m 2 ) SI Unit of speed: meter/second (ms -1 ) To convey certain physical property of an object. Units of length: meter, foot, inches, lightyears…. SI -Système I nternationale (or MKS=Meters-Kilograms-Second) CGS – Gaussian system (Centimeters-Grams-Second) US Customary (foot-slug-second) Units
